Throughout the description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. In other instances, well-known structures and devices are not shown or are shown in a block diagram form to avoid obscuring the underlying principles of the present invention.

APPARATUS AND METHOD FOR DETERMINING A WIRELESS DEVICE'S LOCATION AFTER SHUTDOWN

The embodiments of the invention described below allow wireless devices such as the iPad® or iPhone® (designed by the assignee of the present application) to automatically turn back on, send their location information, and turn off again after being initially shut down. In one embodiment of the invention, the software or hardware activates during the power-down sequence for the wireless device (such as after holding the Lock and Home buttons on an iPhone and entering the power-down screen) where an option appears to either enter a shutdown security code to disable the location security features before shutdown, or to bypass the code and activate the features during shutdown. In one embodiment, failing to enter the correct code after a specified number of attempts automatically activates the security features described herein and, shuts down the wireless device.

In one embodiment, when activated, the device's current location is periodically transmitted over a designated set of communication channels (e.g., email, a designated network address, a text message, etc) and the device thereafter powers down until it is time for the next transmission. The frequency with which the device's current location is transmitted may be specified by the end user or may be set automatically in the software/firmware. The end user may also be provided with the option to disable the features described herein. In one embodiment, the location transmissions continue until the security code is properly entered when the unit is manually powered up by a user, and/or when the code is entered during one of the automatic power-ups.

FIG. 1A illustrates one embodiment of a mobile device 120 which includes a location services module 105 for determining a current location of the mobile device (e.g., using a global positioning system (GPS) signal 1101; a transmit thread 106 for periodically transmitting the mobile device's location; and a timer module 107 for periodically waking the transmit thread 106. As indicated, the timer 107 may be programmed to wake the transmit thread 106 with a frequency configured by the end user 112. In one embodiment, a security component 114 of the device's operating system 104 manages the security code required to disable the periodic transmissions and activates the transmit thread 106 and timer 107 until the correct security code has been entered. In this embodiment, the OS 104 and all of the system components 105-107 are implemented as software executed by the mobile device's processor 100.

Once operational after a device power down, the timer 107 periodically wakes the transmit thread 106. The transmit thread 106 then retrieves the current location of the mobile device 120 from the location services module 105 and transmits the current location over one or more communication channels 155 via a wireless transceiver 150. In one embodiment, the communication channels (which may also be specified by the end user) include an email address 150, instant messaging address 151, short message service (SMS) message 152, and/or a server address 153.

For example, if email is used, the device's current location is stored within the subject line or body of an email and sent to a user-specified email address. If instant messaging is used, the device 120 may automatically log into an instant messaging service (specified by the user) and transmit an instant message to the user's IM account. If SMS is used, the transmit thread may invoke the SMS application on the mobile device 120 to transmit an SMS message to a designated phone number. If a server address is used, the transmit thread will send the device's current location to the server (e.g., to a specific uniform resource locator (URL)) using a pre-specified communication format (e.g., such as an XML document). The user may log in to the server using an alternate wireless device or computer to determine the mobile device's current location. Alternatively, the server may push the device's current location out to the user's alternate wireless device or computer.

In another embodiment of the invention, illustrated in FIG. 1B, the location services module 115, broadcast module 116, timer, module 117 and security module 124 are all implemented as hardware (e.g., as additional circuitry and/or firmware within the mobile device's processor 110, or using separate support circuitry). Aside from the fact that they are implemented in hardware, the functions performed by these modules 115-117, 124 is the same as described above with respect to FIG. 1A. Various additional or alternate implementations are contemplated.

In one embodiment, when the mobile device 120 turns on to send location information, the device will not revert to a fully powered state. For example, the display of the device may remain off. In addition, only those hardware and/or software components required to implement the features described herein may be activated (to save battery power). For example, in the software, implementation shown in FIG. 1, only those components of the operating system 104 required to execute the location services module 105, transmit thread 106 and timer 107 may be executed. In the hardware implementation shown in FIG. 1B, only the firmware and circuitry required to determine the device's current location and transmit that location information over a communication channel may be activated (e.g., such as the cellular or WiFi radio).

In one embodiment, a special graphic may be displayed on the mobile device's display to indicate that periodic location transmissions are occurring. Alternatively, the display may remain off while the device is transmitting its location. Additionally, an option may be provided allowing the user to enter the shutdown code and disable the security features. In one embodiment, when the code is entered the screen can turn on to show that the location security service has been properly disabled.

The shutdown code may be the same or different from the normal unlock code for the mobile device 120. The, code may be numeric or alpha-numeric, a mechanical code (a specific sequence of button presses), a touchscreen code (draw a pattern on the touchscreen either with or without visual cues), a voice activated code, or a camera code that involves taking a picture of a QR code/2D barcode or 1D barcode. In one embodiment, the security features described above may be disabled by taking a picture of an object while the mobile device is in a particular orientation relative to the onboard compass.

Additionally, a two-part or multi-part authentication may be implemented. During the first authentication stage the screen may remain of remain on but offer no cues, or a graphic may be displayed to enter the code. After the first authentication is complete the unit, may request the second authentication (e.g., by turning on the display and displaying a graphic, vibrating, turning on the camera if a QR code is required, or having a voice prompt you over a speaker).

In one embodiment, the techniques described herein may be used in combination with hardware and/or software which performs ‘remote wipes’ on mobile devices. For example, in one embodiment, the mobile device 120 logs into an authorization server when it wakes up. The authorization server may then instruct the remote device to delete all user sensitive data (if previously instructed to do so by the end user) or to disable the security software described herein. The mobile device 120 may also check for authorization from the user when it automatically powers on and sends its location. The user may then remotely disable the security software or change the frequency the unit sends its location information.

While some embodiments described above provide a visual indication that a code is required, in one embodiment, no visual indication is provided to avoid alerting parties that the unit will be tracked after being shut down. When an incorrect code is entered the wireless device may remain in a sub-state with the display turned off (instead of shutting down completely) but with the wireless device still sending location information and the ability to enter the correct code. The wireless device may remain in this sub-state either continually or may be set to power on and enter this sub-state at specific time periods (such as the first 5-10 minutes of every hour). The software/hardware described herein may lock out the device for a specific amount of time after a specific number of failed unlock attempts, and may also be configured to wipe user-sensitive data (or all data) after a specific number of failed unlock attempts,

In one embodiment, information may be collected to supplement the location data. For example, the camera(s) of the device may be configured to automatically snap a picture and transmit the picture over one or more of the communication channels. In one embodiment, the mobile device is configured to send out its final location and IP address of the computer it is attached to just prior to a master reset (i.e., when the security software is still activated).

One embodiment of a method for transmitting a wireless device's location after power down is illustrated in FIG. 2. At 201, a timer and communication channels over which to transmit are programmed based on user input. For example, the user may specify that the device should wake up and transmit a location message over email and to a server every 15 minutes after being powered down. At 202, after the device is powered down, the timer generates a wakeup signal to wake up the transmit thread and radio transceiver. At 203, the transmit thread determines its current location (e.g., from the location services module 115) and, at 204, the transmit thread transmits its current location over the specified communication channels.

One embodiment of the invention utilizes radio frequency identification (RFID) and/or near field technology (NFC) as a “honing” to locate devices at higher resolutions. For example, in one embodiment, other devices (not shown) may use RFID and/or NFC to communicate with and identify the mobile device 120 and then transmit the identity of the mobile device 120 over one or more of the communication channels 155. The mobile device 120 of this embodiment does not need to fully power all of the components illustrated in FIG. 1B, thereby allowing the device to be located when its battery is drained.

In addition to location data, one embodiment of the invention transmits hardware-specific serial numbers encoded with user information (e.g., so the server can identify the user to communicate the location information with). Additionally, the above concepts may also be used to activate certain parts of the system to make it easier to locate the mobile device 120. For example, using RFID/NFC, a hardware signal can be activated to enable the audio portion of the system to help locate the device e.g., by generating an audio signal from the mobile device 120 or the other devices communicating using RFID/NFC).

DIFFERENT API EMBODIMENTS

Different embodiments described herein include an application programming interface (API) implemented by a software component (hereinafter “API implementing software component”) that allows a different software component (hereinafter “API calling software component”) to access and use one or more functions, methods, procedures, data structures, and/or other services provided by the API implementing software component. For example, an API allows a developer of an API calling software component (which may be a third party developer) to leverage specified features provided by an API implementing software component. There may be one API calling software component or there may be more than one such software component. An API can be a source code interface that a computer system or program library provides in order to support requests for services from a software application. An API can be specified in terms of a programming, language that can be interpretative or compiled when an application is built, rather than an explicit low level description of how data is laid out in memory.

The API defines the language and parameters that API calling software components use when accessing and using specified features of the API implementing software component. For example, an API calling software component accesses the specified features of the API implementing software component through one or more API calls (sometimes referred to as function or method calls) exposed by the API. The API implementing software component may return value through the API in response to an API call from an API calling software component. While the API defines the syntax and result of an API call (e.g., how to invoke the API call and what the API call does), the API typically does not reveal how the API call accomplishes the function specified the API call. Various function calls or messages are transferred via the one or more application programming interfaces between the calling software (API calling software component) and an API implementing software component. Transferring the function calls or messages may include issuing, initiating, invoking, calling, receiving, returning, or responding to the function calls or messages. Hence, an API calling software component can transfer a call and an API implementing software component can transfer a call.

By way of example, the API implementing software component 2010 and the API calling software component may be an operating, system, a library, a device driver, an API, an application program, or other software module (it should be understood that the API implementing software component and the API calling software component may be the same or different type of software module from each other). The API calling software component may be a local software component (i.e., on the same data processing system as the API implementing software component) or a remote software component (i.e., on a different data processing system as the API implementing software component) that communicates with the API implementing software component through the API over a network. It should be understood that an API implementing software component may also act as an API calling software component (i.e., it may make API calls to an API exposed by a different API implementing software component) and an API calling software component may also act as an API implementing software component by implementing an API that is exposed to a different API calling software component.

The API may allow multiple API calling software components written in different programming languages to communicate with the API implementing software component (thus the API may include features for translating calls and returns between the API implementing software component and the API calling software component); however the API may be implemented in terms of a specific programming language.

FIG. 3 illustrates one embodiment of an API architecture which includes an API implementing software component 310 (e.g., an operating system, a library, a device driver, an API, an application program, or other software module) that implements the API 320. The API 320 specifies one or more functions, methods, classes, objects, protocols, data structures, formats and/or other features of the API implementing software component that may be used by the API calling software component 330. The API 320 can specify at least one calling convention that specifies how a function in the API implementing software component receives parameters from the API calling software component and how the function returns a result to the API calling software component. The API calling software component 330 (e.g., an operating system, a library, a device driver, an API, an application program, or other software module), makes API calls through the API 320 to access and use the features of the API implementing software component 310 that are specified by the API 320. The API implementing software component 310 may return a value through the API 320 to the API calling software component 330 in response to an API call.

It will be appreciated that the API implementing software component 310 may include additional functions, methods, classes, data structures, and/or other features that are not specified through the API 320 and are not available to the API calling software component 330. It should be understood that the API calling software component 330 may be on the same system as the API implementing software component 310 or may be located remotely and accesses the API implementing software component 310 using the API 320 over a network. While FIG. 3 illustrates a single API calling software component 330 interacting with the API 320, it should be understood that other API calling software components, which may be written in different languages (or the same language) than the API calling software component 330, may use the API 320.

The API implementing software component 310, the API 320, and the API calling software component 330 may be stored in a machine-readable medium, which includes any mechanism for storing information in a form readable by a machine (e.g., a computer or other data processing system). For example, a machine-readable medium includes magnetic disks, optical disks, random access read only memory, flash, memory devices, etc.

In FIG. 4 (“Software Stack”), an exemplary embodiment, applications can make calls to Services 1 or 2 using several Service APIs and to Operating System (OS) using several OS APIs. Services 1 and 2 can make calls to OS using several OS APIs.

Note that the Service 2 has two APIs, one of which (Service 2 API 1) receives calls from and returns values to Application 1 and the other (Service 2 API 2) receives calls from and returns values to Application 2. Service 1 (which can be, for example, a software library) makes calls to and receives returned values from OS APE 1, and Service 2 (which can be, for example, a software library) makes calls to and receives returned values from both OS API 1 and OS API 1 Application 2 makes calls to and receives returned values from OS API 2.
